Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study tests whether smartphone usage data can help tell the difference between normal memory complaints, mild cognitive decline, and Alzheimer's disease. Researchers will collect data from 90 participants' phones over three months. If it works, it could offer a simple, low-cost way to screen for memory problems.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this could lead to a simple, non-invasive way to help detect Alzheimer's disease earlier using everyday smartphone data.
What could go wrong
This is a small pilot study, so results may not be conclusive or generalizable. Smartphone data may not be reliable enough to replace standard diagnostic methods.

This is an AI summary of the original study and may miss details. Read our disclaimer.
